I have an idea to create a physical adept type of character. Some of you may be familiar with Shadowrun and how the physical adepts in that system could use magic to augment their physical abilities for a time. How realistic is it to do this with biomancy? Basically I would be looking at increased strength and speed for the duration of a scene. I am not sure if even the lower level powers for these two would be realistic since we are still talking about augmenting the human body.
Any ideas on how to go about this would be appreciated.
